    • Configure the discovery.event.pin.jobs system property to enable event processors to execute on specific nodes and distribute the work evenly. The scale factor calculates the number of nodes but doesn't pin jobs to specific nodes.

    Before you begin

    Confirm the following:
    • Discovery Admin Workspace is using version 1.9.0 or later.
    • ServiceNow AI Platform® is using version XP9, YP4, or later than YP4.
    • The discovery.use.event.processing system property is turned on. For more information, see Configure Discovery to use Event Framework.

    Role required: discovery_admin

    About this task

    The discovery.event.pin.jobs system property determines how jobs are assigned to nodes. When that property is set to true, jobs are evenly distributed across specific nodes, but scheduling flexibility is limited. When the property is set to false, jobs are randomly assigned, which can increase Discovery throughput.

    Procedure

    1. Navigate to All > System Properties > All Properties.
    2. In the System Properties [sys_properties] table, select the discovery.event.pin.jobs property.
    3. Set the Value field to true.
    4. Select Update.
